Littlebat, who lives in the attic of the public library, loves to poke his head through a hole in the floor and listen to the librarian read stories to the children. One day he gets so excited by a picture in a book that he loses his grip and plummets into the room below. The children scream and the librarian shoos him away. Littlebat's mother says he must wait for "changes" before going so close to a book again. So Littlebat waits. The seasons slowly change, from spring to summer to fall. At last the nights are longer and cooler and the leaves have turned red and gold. Pumpkins appear. It's time!
